The measured volumetric flow rate of ethane at 5.00 atm absolute and 85.0°c is 5.00 x 103 l/h. using an estimated value of the second virial coefficient in the truncated virial equation (equation 5.3–2), calculate v∧ , estimate the compressibility factor z, and determine the mass flow rate of ethane in kg/h.
